Can anyone rec me a draama that is about business/power struggles? even if it is only a subplot

Some of these include

- Hotel King

- birth of a beauty

- the heirs

- Yong Pal

- King2Hearts

- Doctor Stranger

Most of these have either pwoer struggles or business as a subplot

Anything similar will be good thanks


Golden Empire --- All business
Midas  ---  Business and romance
East of Eden ---  business and political power struggles interwoven w/ romance and revenge melodrama.
A Man's Story --- Revenge and business

Rich Man Poor Woman --- J-dorama ... business romance.

EDIT from @Panda below: Giant is same writer as East of Eden ... I heard it is even more business oriented, but I haven't seen it yet!
Thanks for the recommendations, I'll take a look through them :D
Monster (http://mydramalist.com/16419-monster) - revenge and business
Triangle - business and revenge
Can You Hear My Heart - business, some revenge, power struggle
Glory Jane - business, some power struggle
Kill Me, Heal Me - some business, power struggle
Mask - business, power struggle, revenge
Protect the Boss - business, some power struggle
Brand - business
New Tales of Gisaeng - business
Equator Man - business, some revenge
Advertising Genius Lee Tae Baek - business, power struggle
Passionate Love - business, power struggle
99.9: Criminal Lawyer (lawyers who fight for justice, but this one has great cast and chemistry and dad jokes lol)
Bloody Monday (a genius hacker vs villain who's as smart as him, it's similar to death note which is also a power struggle drama)
Hanzawa Naoki (this is very business, also lawyer but he's very good and it's interesting, if you like business with comedy then I'd also recommend Legal High)
(Jdrama) Roosevelt Game - about CEO saving his company from bankruptcy (the drama is adapted from the same novelist who wrote Hanzawa Naoki series)
Innocent Man
Hundred Year Inheritance 
Baby-faced Beauty
Brilliant Legacy
Cinderella's Sister
Cunning Single Lady
Falling for Innocence 
High School King of Savvy 
Rooftop Prince
Secret

These are all kdramas and majority have business hijinks as sideplots
Lady Joker
Hanzawa Naoki
Mondai no Aru Restaurant
Tamiou
+Falling For Innocence and Cunning Single Lady, love those two
Giant is fantastic, and while it also deals with politics and revenge, much of the focus is on the construction business and the cut-throat competition to transform Seoul into a modern metropolis.
